Touch fastener part

Abstract

A touch fastener part has a first substrate tape (10) with hooking elements (12) arranged on one side and has a second substrate tape (16) connected to the first substrate tape (10). The second substrate tape (10) has a connectors (20) on its side facing away from the hooking elements (12) and is wider than the first substrate tape (10). At least one free lateral edge area (22) of the second substrate tape (16) projects beyond the adjacent longitudinal edge of the first substrate tape (10). The two substrate tapes (10, 16) can be bent along and transversely to their longitudinal orientation by at least one free side edge area (22) of the second substrate tape (16) being provided with a weakening of resistance (27) in such a way that bending the two substrate tapes (10, 16) transversely to their longitudinal orientation is facilitated.
